Blue Book 2026: Tiffany & Co.’s Hidden Garden Bursts into Life for Autumn

After butterflies, budding flowers and the first signs of growth, Tiffany & Co.’s Blue Book 2026 High Jewellery collection returns for autumn with its Hidden Garden now in full bloom. Fruit hangs from vines, dahlias unfurl around vivid green gemstones and even the humble pineapple is granted High Jewellery status. If spring was about watching Tiffany’s garden come to life, autumn is the moment to enjoy what it has produced.

Chief Artistic Officer Nathalie Verdeille and the Tiffany Design Studio move between the familiar and the fantastical in this final Blue Book instalment, taking in trailing vines, woven nests, luscious fruits and extravagant flowers along the way. Some stay close to their natural counterparts, while elsewhere the references emerge through colour, pattern or texture. There is variety in the gemstone choices, too, with diamonds and sapphires sharing the garden with cabochons of chalcedony, turquoise and rose quartz.

Nowhere is autumn’s abundance more apparent than in Hanging Garden, a suite of five jewels inspired by tropical fruit suspended from a vine. In the necklace, great drops of lavender chalcedony hang from curling, diamond-set branches. Together weighing 85.07 carats, the plump chalcedony cabochons have the soft translucency and blue-purple tones of ripe grapes, punctuated by smaller cabochon rubies from Mozambique. Lavender paillonné enamel echoes the colour of the chalcedony along the length of the necklace, alternating with sections of diamonds as leaves detailed in yellow gold curl around the fruit below.

Hanging Fruit turns up the colour even further. Inspired by Jean Schlumberger’s archival Two Fruit clip, the five-piece suite presents a punchy palette of orange spessartines and turquoise cabochons against white diamonds. Twisting strands of yellow gold weave through the diamonds, recalling Schlumberger’s iconic Cross Stitch motif, but here the goldwork is looser and more organic. In the necklace, eight unenhanced spessartines totalling 37.58 carats lead towards three smooth turquoise drops, while the brooch is more representational, with turquoise beads clustered beneath a 5.60-carat spessartine.

The natural references become more abstract in Nest, where the loosely woven branches of a bird’s home are translated into something verging on the geometric. Rows of diamonds overlap around cushion-cut Fancy Yellow diamonds, with slender lines of yellow diamonds cutting through the white brilliance. In the necklace, voluminous layers of diamonds build around five Fancy Yellow diamonds totalling 10.42 carats, while the earrings coil the same idea into a pair of circular forms.

Diamonds also dominate the Bee and Vine chapters. Bee revisits the architecture of the hive, with Fancy Yellow and white diamonds arranged into repeating honeycomb-like patterns. Vine takes a more organic route, celebrating Tiffany’s reputation as the ‘Diamond Kings’. Hand-engraved yellow-gold tendrils intertwine with others set with baguette-cut and round diamonds, with marquise-cut diamond leaves sprouting between them. They multiply towards the front of the necklace, becoming more elaborate before culminating in a flower-like cluster, set with a pear-shaped diamond at its centre.

The arrival of the Dahlia suite is particularly well timed for the September unveiling. These late-summer flowers are still in full bloom as autumn approaches, and here Tiffany recreates their frilly petals in diamonds edged with yellow gold, gathered around vivid green tsavorites. Inspired by historic floral motifs and Jean Schlumberger’s ribbon designs, three dahlias cascade down the décolletage, set with unenhanced oval tsavorites totalling 11.16 carats.

The Pineapple suite is more playful, with only the suggestion of the fruit left behind. Tiffany takes the criss-cross geometry of its skin and extends it across a necklace, ring, earrings and bracelet, with ribbons of yellow gold forming a lattice over lavender paillonné enamel and diamonds. Unenhanced Sri Lankan sapphires punctuate the pattern alongside tiny gold studs that reference Jean Schlumberger’s celebrated enamel bangles of 1962.

Finally, the Paradise Birds that appeared earlier in Hidden Garden return for Tiffany & Co.’s autumn finale, this time perched on two extraordinary cabochons. One bird, with a carved chalcedony beak and an inquisitive expression, stands on a 37.01-carat rose quartz cabochon. Its colourful companion balances on 31.48 carats of deep blue chalcedony, with plumage depicted in emeralds, blue and orange sapphires, mother-of-pearl and diamonds.

These two precious visitors to Tiffany & Co.’s garden bring its 2026 Blue Book full circle. What began in spring with buds, butterflies and the first stirrings of growth concludes several seasons later with ripe fruit, open flowers and birds settling among them. Over the course of the year, Hidden Garden has blossomed into a wonderfully rich celebration of the natural world and all the beauty it holds.
